I'm about to swap in fine spline birfields from a 76/77 into a 1970 FJ40. Do I need a centering tool for alignment, or can I just place the shims back into the same order I removed them? I've read up, just dont know if it is totally necessary.

Thanks,
Chad
 
The knuckle centering tool is only required when you are installing new or different knuckles on your axle housing than what came from Toyota. During manufacturing, Toyota centers the knuckle set on each housing, so if the knuckles themselves are changed, or you take them off and forget which shims went where, they need to be centered again.

You can change your birfields till blue in the face and not worry about centering your knuckles :)
 
I am about to start the same thing, replacing the birfields and inner axles on my 79 fj40. Interested to see if you found anyone to rent that centering tool or what you end up doing.
 
The club now owns a centering tool!! If you become a member, the club will loan it to you.

However, if you're just replacing the birfields and inner axles, you do not need the centering tool. You only need it if you are replacing the knuckles.
 
Thanks for the reply CAW16. Yeah I saw that he has them last night while going down the rabbit hole of fj40 research. I may just do that as well.
 
IIRC that's the one we bought as a club. Club membership is much cheaper than that tool.
